Allergies come in all shapes and sizes, but there are a few things you can do to make your home as allergy-free as possible. These simple activities apply whether you live in a studio apartment or a sprawling estate.

Your family and your guests with allergies will be happy you took the time to go through these steps:

Air FiltersMany allergens enter your home through your air vents; using clean air filters is one way to keep them out. Look for are high-efficiency particulate air (HEPA) filters, which are specially designed to remove allergens from the air.

Good filters are most important in your bedroom, which is where you spend the most time and often one of the worst rooms in terms of allergens. It’s also important to keep your home’s humidity at or below 50 percent to prevent mold from growing and spreading.

Less Clutter, Less DustIf you were looking for a reason to go through the piles of junk that seem to spring up in your home, you’ve found it. The less stuff there is in your house, the fewer surfaces dust can gather.

If you’re not sure where to start, focus on rags, clothes, and other porous items. Once you’ve cleared up space on the floor, make sure to dust and clean the space thoroughly — and try to avoid letting clutter pile up again.

Bedding As we said, the bedroom is one of the worst places in your home when it comes to allergens. Keep them at bay by regularly washing your blankets and mattress pad and encasing pillows, mattresses and box springs in dust-mite-proof covers.

Keep stuffed animals in your child’s room to a minimum, as they can be breeding grounds for dust, and commit to regularly washing any that they do have.

If you have pets, you might want to consider keeping them out of your bedroom to prevent them from bringing hair and dander into the room where you spend most of your time.
